Electrics: 850: - T5r Cluster And Diagnostic Socket A, NO CLUSTER & FAULTY DIA

T5r Spain · Jan 30th, 2012, 17:39

My 850 T5R cluster doesn´t work properly since I bought the car.
I´ve got No RPM, NO Speed NO Fuel and NO temperature indication. You turn the ignition key and engine starts up fine. Engine check lights turns on and thats it.

Got the Dash cluster out and back connections are fine.
Noticed because of summer high temperatures that the black plastic on back of cluster is deformed. I guess according to S60 Forum it might be Voltage regulator or IC chip leads.

OTHERS SAY ITS THE ABS MODULE OR IGNITION SWITCH OR circuit board (thin green board, much like a computer board) in the back of the cluster breaks.

Iam getting a quote on a new Dash belonging to a 850T5 I guess its the same as the T5R Dash, anyone has a clue .........?

I went to check the codes and I´ve got a problem with diagnostic socket A. I put the jumper into A7 and push the black button for one second but the red LED light DOESN´T BLINK back information.
It also happens with A6 also.
In the other hand IT DOES blink me back the codes with A1,A2, A3 AND B2,B5,B1.
A1 gave me 2-3-2 (Speedometer signal missing) A3 gave me 4-4-4 (ABS) No power to valves in hydraulic system.

I,m trying to avoid the Volvo dealer as 1 hour of labour in Spain by the Volvo mechanic is 95US$.
I Need some urgent help...........Thanks
